Unformatted text preview: Do: 1. What is the appropriate trig change of variable to simplify x 2 2 ! 5 x 2 ( ) 3 2 dx " 2. What new integral is obtained? Ex. Suppose I used x = 3sec ! to make the substitution and I ended with the following integral: + sin 2 ( ) + tan + C Convert the expression back to an expression in x. Ex. Suppose I used x = 5 tan to make the substitution and I ended with the following integral: cos !" 3sin ( ) + + C Convert the expression back to an expression in x....
